In mid-October we lost energy to the house. Powerwalls failed, but worse, the bypass lever inside relay box did not work, so the Powerwalls also took down access to the PG&E grid. Without any guidance about how to get access to the grid, Tesla support gave us a non-negotiable visit date of today (November 17). Two days ago I confirmed that Tesla would show up today. At ~9:00 this morning Tesla support sent me a text that they would need to reschedule at an undefined date because they do not have a part. Tesla seems to take no responsibility of remorse for this performance. This is beyond outrageous!
